In an editorial titled “We Need to Talk About Corruption in Health Systems” the authors Hutchinson, Balabanova, and McKee hope to encourage a wider conversation about corruption in the health sector. Such conversations are difficult to hold for at least five reasons; it is hard to define corruption; corruption may allow some fragile health systems to subsist, shifting blame – are those involved...

after introducing three famous grammarians –ibn-e-malek, ibn-e- aqil and al-soyuti– the authors of this article try to compare and contrast the tow well-known explications of ibn–malek`s alfiyya, by ibn-e-aqil and al-soyuti. the authors refer to the similarities and differences between the two explications and give examples from both works. the main purpose of this article is introduce th...

In the paper, the authors view some ordinary differential equations and their solutions from the angle of (the generalized) derivative polynomials and simplify some known identities for the Bernoulli numbers and polynomials, the Frobenius-Euler polynomials, the Euler numbers and polynomials, in terms of the Stirling numbers of the first and second kinds.

In this expository paper we show how one can, in a uniform way, calculate the weight distributions of some well-known binary cyclic codes. The codes are related to certain families of curves, and the weight distributions are related to the distribution of the number of rational points on the curves.

Radio pulsar observations can be used to test aspects of general relativity from equivalence principle violations to binary orbital effects in the strong-field regime. This article summarizes the status of such tests at the start of the meeting, and describes two new tests made possible by recent observations of well-known binary pulsar systems.
